This invention relates to endoscopes having a hollow shaft to receive a flexible forceps, probe or the like passed therethrough with the distal end of the forceps or the like projecting from the shaft, and means for pivotally displacing this distal end of the forceps, probe or the like. According to the invention, two rods pass through the shaft parallel to its longitudinal axis and are joined together into a U-shape at their distal end, the latter being bent over at an angle away from the longitudinal axis of the shaft to bear against the end of the forceps distally projecting from the endoscope shaft when in position. These rods are connected to a slider in the proximal end of the endoscope shaft, and the slider is displaceable parallel to the longitudinal axis of the shaft towards the proximal end against a spring by means of an external handle. The two rods may be joined together at their distal ends directly or by an intermediate web and they may be connected to the slider in a releasable manner.

DETAILED DESCRIPTION To achieve this and other objects, the invention accordingly consists in an endoscope having a hollow shaft to receive a flexible forceps, probe of the like passed therethrough with the distal end of said forceps or the like projecting from said shaft, and means for pivotally displacing said distal end of said forceps probe or the like wherein two rods pass through said shaft parallel to the longitudinal axis thereof and are joined together into a U-shape at their distal end said distal end of said rods being bent over at an angle away from said axis of said shaft to bear against said end of said forceps distally projecting from said endoscope shaft when in position, said rods being connected to a slider in the proximal end of said endoscope shaft, said slider being displaceable parallel to said longitudinal axis of said shaft towards the proximal end against a spring by means of an external handle.
